INTE'RLOCKING JOINT *FOR RAILWAY-RAILS.

SPEGIFICATIGN forming part of Letters Patent No. 665,160, dated January1, 1901.

Application led July Z7, `1900. Serial No. 25,026; (No model.)

T0 all whom it may con/cern:

Beit known that I, FRANK C. ANDERSON, a citizen of the United States,residing at Cinciunati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Interlocking Jointsfor Railway-Rails, of which the following is a full, clear, and exactdescription, reference vbeing had to the accompanying drawings,

forming part of this specification.

My invention relates to improvements in interlocked joints for themeeting ends of railway-rails, whereby the rail is held absolutely tightand is prevented from working loose at the joint andis rendered stronger than it is at any other'point in the track and also whereby it isrendered extremely difficult for a train-wrecker to disconnect the railsat the joint, the whole forming a simple, cheap, and efficient jointtending greatly to increase the safety of travel and permit high speeds.

The novelty of my invention will be hereinafter more fully set forth,and specifically pointed out in the claims.

In the accompanying drawings, Figurelis a sectional end View through arail and my improved interlocking joint applied thereto. Fig. 2 is aperspective view of the chair or bed piece which contains the ends ofthe rails at the joints. Fig. 3 is a perspective View of one of thefilling tie-plates. Fig. 4 is an enlarged elevation of one of thedivided keys or pins. Fig. 5 is a side elevation of one end of one ofthe filling-plates, showing the location of the key or pin in one of theelongated openings.

The same letters of reference are used to indicate identical parts inall the figures.

Referring to Fig. 1, A represents an ordinary T-rail of the usual or anysuitable coustruction, of which a is the vertical web, b

i `the double iange or foot, and c the head or tread-piece. Through theweb of each rail, near its ends, are the'usual perforations, eitherround, oblong, or any other shape in cross-section for the`passage ofthe fastening pins or keys B, by means of which two lling tie-plates Cafter the manner of fishplates are secured one on each side ofthe webct. These filling tie-plates, as seen in Figs. l and 3, are composed ofa vertical web c',

whose lower edges are beveled to fit flushupon the flanges of the'footpiece o and whose upper edges are beveledl to t under the uuderside of the head of the rail, and in addition they haveoutwardly-extended portions with undercut beveled lower edges, as seenat c2.

When the ends of two rails are brought together, the filling tie-piecesare placedon each side, so as to overlap the joint after the manner offish-plates, and elongated perforations h, through the webs of thetie-plates, are caused to register with the perforations in the web ofthe rail. Pius B, Fig. 4, having flaring lower portions g at their outerends, are then passed through the perforatious h in the tie-plates andthe perforationsiu the web of the rail, the pins being made smallenoughfor this purpose, and then keys e are driven in on top of the pins B tolock the latter in place, the Haring ends g occupying depres# sions i,Fig. 3, inthe outer edges of the perforations h. A chair-piece D in theform of a partial sleeve with a flattened bottom portion to it over andsnugly embrace the foot of the rail and whichy has been previouslyslipped over the end of one of the rails past the joint, is now slippedback and is driven over the webs of the filling tie-plates and over theends of the keys or pins B, thus completely covering the latter. Theupper edges of the upturned ends of the sleeve D are beveled to fitunder and engage the undercut edges c2 of the tie-plates, thus forming acornplete interlocking of all the parts.

Portions, as at d', Fig. 2, are cut in the edges of the flanged parts ofthe sleeve D to expose the edges of the foot of the rail and to receivethe heads of the spikes by which the rail is fastened to the ties in theordinary manner. By this latter construction also the heads of thespikes are confined in recesses and prevent the endwise slipping of thechairpiece or Sleeve D.

While I prefer that the filling-*pieces C should have the outerprojecting portions to engage the top edges of the chair-piece orsleeve, my invention is Vnot to be limited to this construction, and agreat part of its advantage would be obtained if the filling-pieces weresimply flat and extended between the IOO foot of the rail and theunderside of the head, and in the latter case it Would be desirable toextend up the vertical parts of the chairpiece or sleeve until theyrested directly under the head of the rail. Again, WhileI have shown thelocking-pins as round in cross-section to fit round perforatious in theweb of the rail, it is to be understood that this shape is not materialand that the perforations in the Web of the rail may be rectangular andoblong or oi any shape desired, the pins being given a correspondingshape in cross-section. By means of the elongation of the perforationshin the tie-pieces the 4rails may eX- pand or contract longitudinallywithout buckling or curving, and at the same time they will be heldfirmly and rigidly at their joints to the cross-ties, and a completeinterlocking of the parts at the joints is thus effected.

Having thus fully described myinvention, I claim- Y l. An interlockingjoint for the ends of railway-rails comprising a chair-piece or sleevetred over and embracing the flanges of the foot of the rail and llingtie-pieces uniting the webs of two adjacent rails by means of pinspassed through perforations in said tie` pieces and theWebs of therails, said fillingpieces being embraced by and held between lthe`upright portions of the chair-piece Whose upright portions cover andconceal the ends of the pins, substantially as described.

2. The herein-described interlocking joint for the ends ofrailway-rails, composed of the chair-piece D adapted to slip over andengage the flanges of the foot of the rails and having vertical portionsextending up on each side and at some distance from lthe web of H therails,fllingtie pieces C Aunited to the of the chair-piece,substantially asdescribed.
